Embodiment Construction

[0017] The manufacturing method is described below. As can be understood from the description herein, the method has a variety of applications, but is generally used as a method of manufacturing workpieces such as fasteners or flange nuts. It should be understood that the method can be used to make other parts such as washers and other nuts. At least some embodiments of the methods provided herein can produce workpieces with thickened walls. As described below, this can be accomplished through its various steps, including multiple stampings of the blank using a number of successive stamping dies. In another aspect, a punch and die set for making a workpiece, such as a fastener with thickened walls or a flanged nut, is described below. Yet another aspect relates to fasteners or flange nuts with thickened walls manufactured by stamping and forming.

[0018] exist Figure 1 to Figure 2 In , a workpiece according to a first embodiment of the invention is shown and is indicated...

Abstract

The present disclosure provides a method for manufacturing a work piece, such as fasteners or flange nuts. The method produces a work piece with a thickened wall. This can be accomplished using a plurality of successive stamping dies to reduce the diameter of a cup-shaped feature drawn from a blank, and reforming the cup-shaped feature to a formed shape having a thickened wall. A fastener or flange nut with a thickened wall manufactured by stamping and forming is also disclosed.

Description

technical field [0001] The present disclosure generally relates to methods for manufacturing workpieces such as fasteners or flange nuts. Background technique [0002] Fasteners are used in many applications, for example to fasten components to each other. One common type of fastener is the flange nut, where the flange acts as an integrated washer. [0003] Today's fasteners often come into contact with incompatible materials and / or mating surfaces, where galvanic corrosion is a problem. Fasteners that are in contact with dissimilar materials may be mechanically weaker by nature. Contact corrosion can be avoided when using fasteners made of similar materials. However, this limits where the fastener can be applied. [0004] What is needed is a solution to the lack of mechanical strength and / or limited applicability of fasteners. Contents of the invention [0005] A method for manufacturing a workpiece is provided herein. In an exemplary embodiment, the method includes...
